Question

Quizplus · Accepted Answer

Marine invertebrates are isoosmotic, meaning that their internal fluids have the same osmotic concentration as the seawater around them. This allows for the proper regulation of water and ion balance within their bodies. If they were hyperosmotic (having a higher concentration of solutes than the seawater), they would lose water, and if they were hypoosmotic (having a lower concentration of solutes than the seawater), they would take in too much water and potentially burst.
